Why It's Important to Reset the GMC Yukon Oil Maintenance Light

Resetting the oil life percentage on your GMC Yukon is essential for monitoring the timing of your next oil change and assessing the current condition of your engine oil. This process is also beneficial for planning your upcoming service appointment.

KEEP A PERSONAL RECORD OF ALL MAINTENANCE

Keeping a precise log of all oil changes and related maintenance of your GMC Yukon is advantageous. Organize all essential service records in a systematic manner. This approach ensures optimal upkeep for your GMC Yukon and compiles a detailed maintenance history, which could be beneficial in the event you decide to sell the car later on.

GMC Yukon Oil Type and Quantity

The 2015-2021 GMC Yukon 5.3L requires 8 Quarts of 0W-20 Synthetic oil.

Synthetic or Conventional Oil?

The GMC Yukon requires synthetic oil. Customers always ask me, “Do I need to use synthetic oil?” This is the answer: 

Maintaining consistency in the type of engine oil used is crucial. If your GMC Yukon has been operating on synthetic oil, it’s recommended to continue using it. Conversely, if you’ve been utilizing conventional oil or a synthetic blend, it’s prudent to stick with that type. Do not switch back and forth between types of oil. 

TIP: Bring your own oil to your local shop to save money on oil mark-ups.

How Often Should You Change the Oil on Your GMC Yukon?

It’s highly recommended to change the oil in your GMC Yukon every 3,000 miles. Despite some experts and service centers suggesting longer intervals, sticking to the 3,000-mile schedule is key. Regular oil changes at these intervals are vital for keeping your GMC Yukon’s engine in optimal condition and averting various potential problems. Frequent oil changes maintain engine efficiency and provide an opportunity for a thorough check-up of the SUV at each service. This routine is crucial in detecting and resolving minor issues before they escalate into significant problems.

What to Do If the GMC Yukon Oil Life Reset Procedure Does Not Work?

If you encounter challenges while trying to reset your GMC Yukon oil life percentage, it might be useful to restart the entire process. Start by turning the ignition off with the start button, then on, and off again, before initiating the reset procedure anew. Make sure that the hood and all doors are firmly shut before proceeding.

Why is the GMC Yukon Oil Life Percentage Not Reset?

Simply changing the oil and oil filter on your GMC Yukon won’t automatically reset the oil life percentage back to 100%. If the service reminder on your GMC Yukon stays the same after an oil change, it usually indicates that the reset procedure wasn’t performed after changing the oil, potentially due to an oversight.

GMC Yukon Maintenance Tips

Check Tire Pressure and Tire Tread

You can locate the recommended tire pressure for your GMC Yukon on a white sticker on the door panel, which becomes visible upon opening the driver’s side door. The cold recommended pressure for both front and rear tires is 35 psi. To prevent overinflation, inflate the tires when they are cold, meaning either three hours after the SUV has been driven or before starting to drive. For checking tire tread wear, employ the penny test or utilize a tread depth gauge.

Rotate Your Tires

We advise rotating the tires of your GMC Yukon with every other oil change, assuming you’re following our suggested 3,000-mile oil change interval, or otherwise every 6,000 miles.

TIP: If your local shop or dealership recommends tires on your GMC Yukon, check your tire tread yourself with a tire tread depth gauge!

Check the Coolant Level

Make sure the coolant in the reservoir is filled to the correct level, situated between the minimum and maximum marks. A flashlight may assist in better viewing inside the coolant container. Since the coolant system is a sealed system, a significantly low coolant level could suggest a leak. Conducting a pressure test on the coolant system is an effective method to detect any leaks that may be present.

Check the Brake Pads and Rotors

Inspect the brake pads on the front and rear brakes of your GMC Yukon to verify they have enough material. Employ a brake pad gauge for an accurate measurement of their thickness. Additionally, examine the brake rotors for indications of rust or abnormalities. When your GMC Yukon is elevated on a jack or lift, rotate each wheel by hand (with the parking brake disengaged) to check that they turn smoothly. Any resistance in the movement of a wheel might indicate an issue with the brake caliper or seized slider pins in the caliper.

Check Brake Fluid Reservoir

Maintaining a full brake fluid reservoir in your GMC Yukon is essential. Discovering an abnormally low level of brake fluid typically points to either a leak in the system or extensively worn brake pad material. In these situations, begin by refilling the brake fluid reservoir, then pump the brake pedal, and subsequently examine the brake calipers and lines for any evidence of leaks.

Check Washer Fluid Level

Refill your washer fluid reservoir. During the colder seasons, choose a washer fluid with antifreeze properties to avoid freezing inside the container.

Check the Engine and Cabin Air Filters

Access the air filter box in your GMC Yukon and take out the air filter. If it seems dirty, clean it using compressed air, a vacuum, or by shaking off the dust and debris. Should the filter be excessively dirty, replace it. If it appears fairly clean, just put it back in place. Additionally, inspect the cabin air filter located behind the glove box, which purifies the air inside the vehicle. Change the cabin air filter if it’s dirty or hasn’t been replaced before.

Check Power Steering Fluid

Ensure the power steering fluid in your GMC Yukon reaches the ‘full’ line on the reservoir bottle. A fluid level below normal may suggest a leak in the power steering system. Should you notice a low level, replenish the fluid and afterward inspect the power steering rack and hoses for any leakage signs.

Benefits of Regular Oil Changes

In my ten years as an automotive technician, working in both dealership and independent shop settings, I’ve observed that vehicles without regular maintenance tend to experience more frequent and serious problems. Despite some car manufacturers recommending oil change services every 5,000 to 25,000 miles, I strongly recommend a 3,000-mile oil change interval for the GMC Yukon, regardless of the manufacturer’s advice. This approach is vital for sustaining optimal performance and extending the life of the SUV. Regular oil changes play a crucial role in reducing engine wear in the GMC Yukon and can improve fuel efficiency by up to 2%. They also help maintain a cleaner engine and prevent the build-up of harmful deposits that can shorten the engines life.
